A 27-item therapy rating scale was developed to evaluate therapists' use of two maintenance treatments for recurrent depression: Maintenance Interpersonal Psychotherapy (IPT-M) and Medication Clinic. Analyses of data obtained from student raters indicated that 13 items discriminated between the two therapies (P0.05). Split-sample discriminant function analysis using these items accurately classified 83% of index-sample sessions and 80% of validation-sample sessions. Factor analysis yielded four modality-specific factors, two contamination factors, and one general psychotherapy factor. Four factors related to therapeutic intervention and session focus differentiated IPT-M from Medication Clinic. Findings confirm the psychometric adequacy and sensitivity of the scale; possible use in predicting patient outcome is discussed.
开发了一个包含27个项目的治疗评定量表，以评估治疗师对复发性抑郁症的两种维持治疗方法的使用情况：维持性人际心理治疗（IPT-M）和药物治疗门诊。对学生评分者提供的数据进行分析表明，有13个项目能够区分这两种治疗方法（P<0.05）。使用这些项目进行的分样本判别函数分析准确地对83%的指标样本疗程和80%的验证样本疗程进行了分类。因子分析产生了四个特定模式因子、两个混杂因子和一个一般心理治疗因子。与治疗干预和疗程重点相关的四个因子将IPT-M与药物治疗门诊区分开来。研究结果证实了该量表的心理测量学充分性和敏感性；并讨论了其在预测患者预后方面的可能用途。
